Filed:

Feb 9, 2013

Appl. No.:

13/763643

Inventors:

Tao Li - Gainesville FL, US
Chao Li - Gainesville FL, US

Assignee:

University of Florida Research Foundation, Incorporated - Gainesville FL

International Classification:

G06F 1/26

US Classification:

713300

Abstract:

Various examples are provided for renewable energy control. In one example, among others, a system includes a PV source, a multi-core processor load, and a solar power manager configured to adjust an operating point of the PV source about a maximum power point by dynamically adjusting a transfer ratio and a load level. In another example, a method includes sensing an output current supplied to a multi-core processor load by a power converter at a first transfer ratio, sensing another output current supplied at a second transfer ratio, and determining an operating point of the PV source with respect to a maximum power point based upon the output currents. In another example, a system includes a power manager configured to switch servers between a renewable energy supply and a utility energy supply based at least in part upon a budget level and the load power consumption.

Abstract:

Embodiments relate to a method and apparatus for providing additional power supply to a datacenter receiving power from a power distribution unit (PDU) that provides utility power. The additional power supply can be provided by a renewable power source, such as one or more solar panels. Embodiments can add additional energy storage capacity with the additional power supply and can add additional server(s) with the additional power supply. Embodiments can incorporate a power control hub that controls the delivery of either AC power received from the PDU, or AC power converted from DC power received from the renewable power source and/or DC power received from additional energy storage devices that provide the additional storage capacity to the additional server(s), to the additional server(s).

Abstract:

Embodiments relate to a method and system for power demand shaping (PDS) so as to manage power generation and use. Specific embodiments relate to data center power demand shaping to achieve high-performance low-overhead data center operation. Specific embodiments can incorporate standard (utility power) energy sources, renewable energy sources, or a combination of standard (utility power) energy sources and renewable energy sources. Embodiments of the subject PDS techniques can incorporate trimming the data center load power so as to allow DG systems to follow the power demand efficiently and/or incorporate two adaptive load tuning schemes that can boost data center performance and enable near-oracle operation during power demand trimming process. To implement a cross-layer power optimization scheme, embodiments of the subject invention relate to a power management module that can reside between front-end distributed generation and back-end computing facilities to provide a coordinated tuning between the supply and load.
